C15 ACERT Inframe Kit 16:1 Low Compression 3466615 – MXS NXS BXS SDP

PAI Caterpillar C15 ACERT Low Compression Conversion Kit — 16:1 CR (Piston 3466615) C15107-010 

Applies to ESN Prefixes: MXS / NXS / BXS / SDP

Engineered by PAI Industries, a trusted American manufacturer of premium aftermarket diesel engine components, this Low Compression Conversion Kit is specifically designed to convert C15 ACERT engines from the original 18:1 compression ratio to a more durable 16:1 configuration.

Lowering the compression ratio significantly reduces peak cylinder pressure, combustion temperatures, and internal engine stress — making this kit ideal for high-mileage engines and demanding operating conditions. The result is improved durability, enhanced reliability, and extended engine service life, especially in heavy-duty and severe-duty applications.

This configuration is highly recommended for engines undergoing Twin Turbo ACERT (compound turbo) to Single Turbo conversion, providing a more efficient, reliable, and lower-maintenance setup for fleets and rebuilders.

At the core of this kit are heavy-duty steel pistons, engineered to withstand extreme combustion forces while delivering superior strength, stability, and long-term performance compared to traditional piston designs.
